Giovanni Battista Piranesi and workshop

This complex sheet has several layers of drawing, by different hands. The pen drawings of the recto and verso are by Piranesi himself, but the chalk drawing of the recto must be by a studio assistant. The pedestal on the verso relates to an earlier red chalk drawing also at the Morgan, 1966.11:101. The verso pedestal is itself drawn over an earlier chalk sketch of the Barberini lion bas relief, but which may also be the work of a studio assistant.
The Sphinx-footed pedestal of the verso is akin to numerous ancient Roman examples, among them works in the Museo Archeologico Nazionale in Venice (inv. 1887.114, from the Grimani collection), the Musee du Louvre (inv. MA611), and the British Museum (inv. 1805,0703.223), although the precise model for Piranesi's drawing has not yet been identified. Piranesi may have based this sketch on his own earlier drawing (1966.11:101), for this pen drawing seems to be in his style of the 1770s, when he was at work on the Vasi, Candelabri (and when he was most active as a dealer in real and composite antiquities), although the chalk drawing (1966.11:101) is likely from the previous decade.
